To all whom tt may concern:l

Be it known that LFREDERICK W. WINSE- BROCK, of Brooklyn, in the county of Kings and State of New. York, have invented an Improved Automatic Uarbonic-Acid-Gras Generator, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, and the letters of reference marked thereon, making part of this this specification, in which- Figure l is a cross-section on the line v ab, Fig. 2. Fig. 2 is a cross-section on the line y y, Fig. l, one of the pipes being removed.

The object of my invention is the construction of an automatic device by means of which the carbonio-acid gas can be generated and supplied to the beer-keg at the same time.

The nature of my invention consists in regulating the llow of the acid, at will, into the generator by means of an automatic valve, and also the pressure of the gas, as more fully hereinafter described.

The construction and operation of my invention are as follows: Y

A is the gas-generator, which is constructed out of any suitable material, and in any convenientform. This generator is provided with a bung, K, by means of which it is charged with marble chips, or other suitable carbonate and water, and has at its bottom a discharge-bung, P. B is the acid-chamber, having a bung, H, at its top, by means of which it is charged. To the bottom B of the acidchamber, and Within the generator A, is attached the valve-seat c1, in which rests the valve c, which, as shown in the drawing, is conical in shape. To the valve-stem c3 is secured a cup, c2, which has for its object the reception oi' any acid which may drip from the chamber B, and also preventing anyacid from falling on the lever D, thus destroying the same. D is alever, which is pivoted to the arm d, secured to the top of the generator A, and is attached to the valve-stem c3. The other end of this lever D is secured to a rod, d'. This rod d is attached to and passes up through a flexible diaphragm, E, secured in suitable bearings e c in a short cylinder, c', attached t the top of the generator A. To

the other end of this rod d is secured the regulatinglever G, which is pivoted to an arm, g1, secured to the top of the generator, and provided with movable Weights g2 g2, one at each end of the lever. F is'the equalizingpipe, which extends from the bottom ot' the acid-chamber B to its top, and is connected at its lower end with the generator A.

The object of this pipe is to equalize the pressure of the gas in the chamber B, so as to have the same pressure in this chamber as in the generator. vL is` a cylinder, in which the gas is washed or purified. This cylinder is lilled with water, up to about the point indicated by dotted lines in Fig. l. R is a perforated bottoni secured in the lower section of the cylinder L, through Which the gas, in finely-divided particles, is forced up through the Water in the cylinder and Washed. n is a pipe secured at one end to the dome of the chamber B, its other end extending down through the perforated bottomB, to near the bottom'ot' the cylinder L. mis the bung through which the cylinder is charged, and o is the exit-pipe, both ofy'which are -located in the top of the cylinder L. To the bottom of the cylinder is attached the dischargecock g.

The operation is as follows: The generator A is supplied With a sufficient quantity of marble chips, or other suitable carbonate and water, through the bung K, and the acid-chamber B is supplied with acid through the bung H. The weights gZ g2 on the lever G are adjusted to suit the pressure of the acid required. Then, as the pressure in the generator A becomes less than the pressure ot' the weighted lever G, the rod d is pressed down, which opens the valve c, and allows the acid to flow into the generator, until there is a sufficient quantity of gas generated to overcome the pressure of the weighted lever G. This gas then presses upon the flexible diaphragm E, lifting the lever D and closing valve c. The gas, as generated, passes up through the pipe F, into the top ot' the chamber B, from whence it passes through the pipe n, down to the bottom of the purifying-cylinder L. From thence it passes up through the perforated bottom R in finely-divided particles,

through the Water, by means of which itis Washed or purified, and out through the exittube o into the beer barrel or keg.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

In a carbonio-acid-gas generator, the combination of the lLoidehttmher B, valve c, valvelever D, flexible diaphragm E, Weighted lever G, equalizing-pipe F, and generator A, substantially as described.

In testimony whereof Ihave signed my name to this specification in*` the presence of two subscribing witnesses.
